I'm not sure as I don't know the story. It could be two people with the surname Chambers.
Not having read 'chambers love story', it's hard to determine the main characters. However, in a love story, there are often protagonists. In this story, if it follows a common pattern, there could be a young Chambers who falls in love with someone special. Maybe it's a love that crosses different social classes or cultural backgrounds. For example, a Chambers from a wealthy family falling in love with someone from a more modest background, and their story would be about how they deal with the differences and their love for each other.
As I haven't read 'chambers love story', I can't say for sure who the main characters are. But typically in a love story, there would be at least two main characters. In this case, since it's called 'chambers love story', perhaps there are characters named Mr. Chambers and Ms. Chambers who are involved in a romantic relationship. They might be of different personalities, one could be more outgoing and the other more reserved, and their interactions would form the core of the story.
